In addition, guiding parts 15 is provided with crimp spring 18.Crimp spring 18 pairs of guiding partss 15 stretch.Thus, disengaging pawl 16 rotates together with guiding parts 15, and the front end of disengaging pawl 16 is crimped on paper bundle P on the thickness direction of paper bundle P.If disengaging pawl 16 does not press paper bundle P, then as described later, the front end PT of the paper P1 utilizing paper feed roller 14 to retreat, may slip into the downside of disengaging pawl 16 when conveying forward afterwards.In addition, the accompanying drawing that Fig. 4 is later omits crimp spring 18.
The structure of 2-3. guiding parts
The structure of the guiding parts 15 of the manner is shown at Fig. 4.As shown in Figure 4, disengaging pawl 16, conveying roller 17b and guiding parts 15 one is formed.Disengaging pawl 16 is parts of pressing paper bundle P.In addition, if when paper feed roller 14 once open by overlapping extraction two pieces of paper, disengaging pawl 16 is still for only sending the overlap conveying peventing member to paper transportation path 20 by uppermost paper P1.In the manner, as shown in Figure 4, disengaging pawl 16 and conveying roller 17b and guiding parts 15 one are formed.Further, guiding parts 15 supports as can rotate centered by the S. A. of conveying roller 17b.But the centre of gration of guiding parts 15 is not necessarily identical with the S. A. of conveying roller 17b.As long as near the end being in the side contrary with disengaging pawl 16.In addition, even independently parts are also passable with guiding parts 15 for disengaging pawl 16 and conveying roller 17b.
Guiding parts 15 and disengaging pawl 16 are the resinous films such as mylar or polyethylene foil.In addition, guiding parts 15 and disengaging pawl 16 can adopt the thin plate be made up of stainless steel substrates or steel.In addition, for disengaging pawl 16, the material of the higher material of friction coefficient or effects on surface can be adopted to be finish-machined to the material of the high shape of friction coefficient.This is because paper P1 becomes more easy from the separation of paper bundle P.
3. the paper supply action of paper feed
Then, the paper supply action of paper feed is described.First, as shown in Figure 5, paper feed roller 14 is made to rotate (reversion) towards the direction of the arrow DR in Fig. 5.The rotation amount that paper feed roller 14 is reversed can be prespecified.But the rotation amount of reversion is, the rotation amount of the position in the scope making the front end PT of paper P1 move between the front end of disengaging pawl 16 and paper feed roller 14.That is, while paper P1 needs are in the state discharged from disengaging pawl 16, the state do not discharged from paper feed roller 14 is in.By the reversion of this paper feed roller 14, uppermost paper P1 extracts out from paper bundle P towards the direction away from paper transportation path 20.Thus, paper P1 is separated with paper bundle substantially.Then, the rear end PE of paper P1 touches dip plane 11b and rolls upward.In addition, now conveying roller 17a, 17b does not rotate.
Next, paper feed roller 14 rotates (rotating forward) towards the direction of the arrow DN in Fig. 6.Therefore, uppermost paper P1 sends towards paper transportation path 20.Therefore, paper P1, while separated pawl 16 is separated from paper bundle P, sends towards paper transportation path 20.Then, when the front end PT of paper P1 climbs up disengaging pawl 16, conveying roller 17a, 17b start to rotate towards the direction of the arrow D3 in Fig. 6.Therefore, before the front end PT of paper P1 arrives conveying roller 17a, 17b, conveying roller 17a, 17b have started to rotate.
Further, as shown in Figure 7, when the front end PT of paper P1 passes through the position of conveying roller 17a, 17b, paper P1 utilizes conveying roller 17a, 17b and paper feed roller 14 to be delivered to paper transportation path 20.Now, paper feed roller 14 is towards the direction (rotating forward) of the arrow DN in Fig. 7, and conveying roller 17a, 17b rotate respectively towards the direction of the arrow D3 in Fig. 7.Further, when the front end PT of paper P1 arrives the position of Time Pick-off Units 21, the conveying of paper P1 is temporarily stopped.Further, the opportunity formed with the image of photosensitive drums 31, paper P1 sent towards the position of transfer roll 40 by conveying roller 17a, 17b and paper feed roller 14 accordingly.Afterwards, paper P1 is transferred roller 40 transfer printing toner image.
4. paper loading amount
The number of times that the number being loaded into the paper bundle P of sheet feed cassette 10 is formed with image and reducing.Therefore, the difference of the angle of the disengaging pawl 16 that the paper loading amount by sheet feed cassette 10 causes is described.
4-1. fully laden
Illustrate that the carrying capacity of paper bundle P becomes the situation of its upper limit at Fig. 8.In this case, raise spring 12 and be sufficiently compressed because of the weight of paper bundle P, therefore, raise plate 13 not too large relative to the angle θ A of base plate 11a.Now, the angle between the upper surface of paper bundle P and disengaging pawl 16 is θ 1.
4-2. light condition
Illustrate that sheet feed cassette 10 is only accommodated with the situation that a piece of paper opens P1 with Fig. 9.In this case, raise spring 12 and be in the state of extending substantially completely.Raising now raises the angle θ A of plate 13 relative to base plate 11a when plate 13 is greater than fully laden relative to the angle θ B of base plate 11a.Even if in this case, disengaging pawl 16 also has pressing effect.But, because the below of disengaging pawl 16 does not in this case have paper bundle P, therefore disengaging pawl 16 directly contact raise plate 13.In addition, the angle θ 2 between the upper surface of paper P1 and disengaging pawl 16 is less than the angle θ 1 of at full load.
As above explain, paper transportation path 20 is configured at the top in the scope of the Width of sheet feed cassette 10.Therefore, the change compared with the width of sheet feed cassette 10 of the overall with of the image processing system 100 of the manner is not too large.That is, the size of the image processing system 100 of the manner is less than existing image processing system.
5. variation
The shape of 5-1. sheet feed cassette main body
Here, the variation of the manner is described.In the manner, sheet feed cassette main body 11 is provided with dip plane 11b.But, be not necessarily provided with dip plane 11b.As shown in Figure 10, can be the sheet feed cassette 210 not having dip plane 11b.The sheet feed cassette main body 211 of sheet feed cassette 210, except base plate 211a, leading section 211T, also has not towards the rearward end 211E that the rear end side of paper bundle P tilts.
As shown in Figure 10, when make paper feed roller 14 reverse (direction of the arrow DR of Figure 10) time, uppermost paper P1 sends the opposition side to paper transportation path 20.Now, paper P1 be connected to its rear end PE the rearward end 211E of sheet feed cassette main body 211 state bend.Bent by this, paper P1 is separated from paper bundle P.Because how much electrostatic of paper P1 escapes in air, therefore paper P1 is difficult to again be attached at paper bundle P.In addition, the image processing system possessing this sheet feed cassette 210 is also less than the overall with of the image processing system 100 of the manner.This is the width owing to not needing with being provided with dip plane 11b.
5-2. raise the shape of plate
